Amino Acids and Proteins
In the human organism, proteins undertake multiple and vital functions. Structural proteins are found in each and every cellular compartment. Intracellularly, motor proteins power the energy-dependent transportation of vesicles. Signal proteins receive and transmit information. Transport and storage proteins bind, for example, oxygen, and carry it to a location where…
Gene Mutations and Repair Mechanisms of the Human Cell
Mutations are associated with diseases and defective genes. Mutated genes are actually the cause of many diseases, although they are also necessary. Without a permanent change in the genome, evolution is not possible, and purely static DNA would prevent any development. DNA is also the only molecule of the cell…
Regulation, Apoptosis, Mitosis and Replication of DNA
This course explains the semiconservative replication of DNA and the role it plays in the cell cycle. The phases of the cell cycle and mitosis (prophase, metaphase, anaphase, and telophase), as well as the regulatory mechanisms associated with cyclins and their antagonists, are all relevant topics in medical exams. Table…
Histology
Histology is the study of the microanatomy of cells, tissues, and organs as seen through a microscope. It examines the correlation between structure and function. Histology, also known as microscopic anatomy or microanatomy, is the branch of biology which studies the microscopic anatomy of biological tissues. Histology is the microscopic counterpart to…
Cell Biology
Cell biology is the study of cell structure and function, and it revolves around the concept that the cell is the fundamental unit of life. Focusing on the cell permits a detailed understanding of the tissues and organisms that cells compose. Some organisms have only one cell, while others are…
Molecular Biology and Genetics
Molecular biology and genetics study organisms on a cellular and molecular level. This is a rapidly developing field of biological sciences which has many important applications not only in biomedical sciences, but also in other domains such as agriculture. The study of living things at molecular and genetic levels have…
